ROD-AD JUSTING- DEVICE Application filed January 29, 1908.

To all whom it may concern:

Be it known that I, LELAND Wnlms, a citizen of the United States, and aresident of Grenloch, New Jersey, have invented certain Improvements inRod-Adjusting Devices, of which the following is a specification.

The objects of my invention are to provide a ch ap, strong and simplerod-adjusting device; to prevent weakening of the rod by the formationof openings therein for the reception of the securing bolt; to permit ofrelatively tine adjustments of the rod; to relieve the securing bolt ofa portion of the strain due th the pull or thrust of the rod thereupon,and to permit of any desired angular adjustment of the rod in respect tothe fixed member to which it is confined without impairing the securityof its connection These objects I attain in the manner hereinafter setforth, reference being had to the accompanying drawing, in which Figure1 is a plan or top view of part of a rod with an adjusting devicetherefor cor.- structed in accordance with my invention; Fig. 2 is aview of the device partly in plan and partly in horizontal section; Fig.3 is a transverse section on the line aa, Fig. 1.; Figs. l, 5, 6, and 7are views illustrating modifications of my invention. Figs. 2, 3 and 7are on a larger scale than Figs. 1, t, 5, and 6.

In the drawing, 1 represents a rod, which may be provided at one endwith an eye 2, or otherwise constructed for attachment to or engagementwith any member of a machine which may have to be adjusted to differentposit-ions in respect to a normally ,fiXed member, such, for instance,as the bar 3 shown in Figs. 1, 3 and 5. This bar may, for example,constitute one of the fixed bars of the frame of an agriculturalimplement,

and the rod may be connected to a culti vator bar or other member of themachine whose adjustment to different positions in respect to the fixedmember may be necessary at different times. That portion of the rodwhereby the adjustment of the same is effected, is reversely bent orwaved so as to form a succession of oppositely facing loops 4t, any oneof which may engage the bolt 5, whereby the rod is secured in place,said bolt being carried by the bar 3, and passing through a washer 6,bearing upon said bar Specification of Letters Patent.

and provided with opposite flanges 7, for bearing upon the outer portionof the loop which is in engagement with the bolt and retaining the rodin its proper lateral relation to said bolt, in order to prevent itfrombeing disengaged therefrom, vertical displacement of the rod, so as tofree it from engagement with these flanges, being normally preventedeither by the nut 10 with which the bolt is provided, or by a cap plate9 resting upon the tops of the flanges and confined in such position bysaid nut 10.

In order to effect readjustment of the rod, the nut 10 and cap plate 9are removed and laid rod is lifted so as to be free from engagement withthe bolt and flanges 7, whereupon it can be moved longitudinally inorder to bring any other one of its loops 4: into engagement with thebolt and can be restored to position between the flanges 7 and thereretained by reapplication of the cap plate and nut.

The flanges 7 are preferably of segmental form, in order that either ofthem may conform to the back of the loop which is in engagement with thebolt, the ends of that flange which is not thus in engagement bearingupon the members of the loop at the open end of the same, as shown inFig. 2, whereby said flanges aid the bolt in resisting longitudinalthrust or pull upon the rod. lVhile this is a preferable feature of myinvention it is not absolutely necessary in all cases, as the washermay, if desired, have straight flanges, such, for instance, as shown at7 in Fig. 4, which will still perform the function of maintaining theengaging loop of the rod in its proper lateral relation to the bolt.

As the flanged washer 6 is capable of turning freely with or upon thebolt 5 it permits of any desired angular adjustment of the rod 1 inrespect to the bar 3, or other fixed member of the machine, without inany way impairing the hold of the bolt upon the rod.

The bending or waving of the rod to form the successive loops forengagement with the retaining bolt provides for the desired longitudinal adjustment of the rod without any weakening of the same such aswould be caused by the formation in it of openings for the reception ofthe securing bolt, and this method of construction also provides for arelatively fine adjustment of the rod, the

successive positions of the atter b ing SQIDZ eter oi the rod plus tnediameter 01 t curin bolt. The provision of the rod 7 ly lacing loops is,however, not essential to the broader embed-i rent e1 1 vention, as theloops may, I l i in the same dir ction, a roe thus construc'ed beingshown i E i instead of forming the flanges upon a washer employed inconi'iection with a cap plate, as previously shown and described, saidflanges may, in the case of a metal bar, be formed upon the ar itself,as shown for instance at T in 1 3, or, reversing the washer G, as shownin Fig. T, the cap plate 9 may be dispensed with.

I claim 1. In a rod-adjusting device, the combination of a securingbolt, a rod having successire loops for engagei'nent with said bolt,means for laterally retaining the engaging loop of the rod in suchengagement, and means for preventing displacement of the rod in thedirection of the axial line of that portion of the bolt whicii the rodenga es.

2. In a rod-adjusting device, the combination of a securing bolt with arod having sue essive oppositely facing loops for engagement with saidbolt, and means for preventing lateral displacement oi the rod wheneither of its loops is in engagement with the bolt.

3. In a rod-adjnsting device, the combination of a securing bolt, a rodhaving successive loops for engaging said bolt, and means, also engagingthe belt, for preventing either lateral displacement of the rod ordisplacement of the same in the direction of the axis of that portion ofthe bolt which the rod engages.

r. In a rod-adjusting device, the combination of a securing bolt, with arod having successive loops for engagement with the bolt, and retainersdisposedv on opposite sides of that portion he bolt which engages theloop of the rod and each adapted to bear upon, and laterally retain thelooped rod.

5. In a rod-adjusting device, the combination of a securing bolt, with arod having oppositely-facing loops for engagement with the bolt, andopposed retainers, each adapted e, r l, i a L" .4. ray '1 "hat 100) to ba i oi nd late ll e 111 L of the rod which is in engagement with thebolt, said retainers being curved to conform with the curve of the loop.

6. 1n a rod-adjusting device, the combination of a securing bolt, with arod having successive loops for engagement with the bolt, and opposedretainers, one bearing upon the back or the loop which is in engagementwith the bolt and the other bearing upon the members of the loop at theopen end of the same.

'T. In a rod-adjusting device, the combination of a securing bolt, arodhaving successive loops for engagement with the bolt, and opposedretainers, each constructed either for bearing upon the back of theengaging loop and retaining it in such engagement, or for bearing uponthe members of the loop at the open end or the same.

8. in a rod-adjusting device, the combina tion oi. a securing bolt, arod having successive loops for engagement with the bolt, and opposedretainers, each constructed either tor l earing upon the back of theengaging loop and retaining it in such engagement, or hearing pon themembers of the loop t the open end of the same, each of said 'ainersbeing also curved to conform to the a the back of the loop.

9. A rod-adjusting device comprising a securing bolt, a rod havingsuccessive loops for engagement with said bolt, a washer mounted uponthe bolt and flanged to bear upon and laterally retain the loop which isin engaganent with the bolt, and means for retaining the rod inengagement with said flanged portion or the washer.

10 A rod-adjusting device comprising a' securing bolt, a rod havingsuccessive loops for engagement therewith, a washer mounted upon thebolt and flanged to bear upon and laterally retain the loop which is inengagement with the rod, and a cap plate for retaining the loopedportion of the rod in engagement with said flanged portion of thewasher.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
